Cultivation method of Corylus heterophylla Fish. and Corylus avellana L. hybrid

Abstract

The invention provides a cultivation method of a Corylus heterophylla Fish. and Corylus avellana L. hybrid. The cultivation method comprises steps as follows: land selection, variety selection, variety proportioning and fertilizer application. The cultivation method has the benefits as follows: the nutritional value of fruits is high, the content of moisture in the fruits is 7.5%, the content of starch is 1.0%, the content of total sugar is 12.23%, the content of soluble protein is 55.29 mg / g, and the fat content is 59.14%; the content of calcium and iron is high, 100 g of kernels contain 326 mg of calcium and 9.0 mg of iron; the flowering phase starts 5 days earlier every year, and fruiting starts 10 days earlier every year; the fruit setting rate is high, the yield of fruits is large, each fruit weighs 2.7 g on average, each fruit shell is 1 mm thick, the kernel percentage is 47%, and the yield of each tree growing for 5-6 years is 2.7 kg; the cold resistance of fruit trees is high; the cultivation method has an improvement function on soil in a planting area.

Description

technical field [0001] The invention relates to a method for cultivating Pingou hybrid hazel, which belongs to the technical field of forestry planting. Background technique [0002] At present, the world's hazelnut cultivation area reaches 620,000 hm2, and the total annual output of hazel nuts is 978,000 tons (2008), and the output varies in different years. Among them, Turkey occupies the first place in terms of area and output, with a cultivated area of ​​405,000 hm 2 , The nut production is 470,000-780,000 tons, accounting for 65.3% of the world's total hazelnut area and 70-74% of the total output. Italy occupies the second place, with a cultivated area of ​​71,400 hm 2 , with an output of 80,000-120,000 tons, accounting for 11.5% and 12-14% of the world's total respectively; the third place in the world is the United States, with a cultivated area of ​​11,000 hm 2 , the output was 39,900 tons, accounting for 1.8% and 4.2% of the world's total respectively.

AI Technical Summary

Problems solved by technology

[0006] (1) The soluble protein, calcium, and iron contents in the fruit are 52mg / g respectively, and the calcium content per 100g of nuts is 316mg, and the iron content is 8.6mg. The nutritional content needs to be further improved;

[0007] (2) The planting period is long;

[0008] (3) The yield needs to be further improved. The hazelnut fruit cultivated by the existing technology has an average single fruit weight of about 2.3-2.5g, a shell thickness of 1.2mm, a kernel yield of 40%, and an average yield of 6-7 years old per plant of 1.5kg;

[0009] (4) The existing Pingou hybrid hazel can generally withstand the low temperature of -30°C, and the one-year-old branches have different degrees of freezing damage, and the wintering ability needs to be further improved to increase the adaptability of its planting;

[0010] (5) The cultivation of the existing Pingou hybrid hazel has no obvious improvement effect on the soil in the planting area
